We divide 78145981 by 687
We want to divide 78145981 by 687.

Step 1:
If we divide 7 by 687, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 687

Let's proceed to step 2:
The number 687 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 687

Advancing to step 3:
781 divided by 687 is 1 with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 687 from 781 to get 94.
Fetch the next digit (4) from the dividend, attach it to 94 and continue: 944 / 687

Moving on to step 4:
687 can be fit into 944 1 times, resulting in a remainder of 257.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 687 away from 944, we end up with 257.
Fetch the next digit (5) from the dividend, attach it to 257 and continue: 2575 / 687

Moving on to step 5:
2575 divided by 687 is 3 with a remainder of 514.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 2061 from 2575 and we're left with 514.
Append the next digit (9) from the dividend to 514 and continue with: 5149 / 687

Going ahead to step 6:
5149 divided by 687 is 7 with a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 1137.0
Deduct 4809 from 5149 and we're left with 340.
Append the next digit (8) from the dividend to 340 and continue with: 3408 / 687

Going ahead to step 7:
If we divide 3408 by 687, we get 4 and a remainder of 660.
The next digit of our result is 4. 
Result so far: 11374.0
Subtract 2748 from 3408 to get 660.
Include the next digit (1) from the dividend after 660, then repeat: 6601 / 687

Let's proceed to step 8:
687 can be fit into 6601 9 times, resulting in a remainder of 418.
Put 9 as the next digit of the answer. 
Result so far: 113749.0
Deduct 6183 from 6601 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 9:
4180 divided by 687 is 6 with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 113749.6
If we take 4122 away from 4180, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
580 divided by 687 is 0 with a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 113749.6
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 11:
When dividing 5800 by 687, we get 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 113749.608
Subtract 5496 from 5800 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
687 goes into 3040 4 times with a remainder of 292.
Record the quotient 4 as the next digit in the result. 
Result so far: 113749.6084
Subtracting 2748 from 3040 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
2920 divided by 687 is 4 with a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 113749.60844
Subtracting 2748 from 2920 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 113749.60844, and the remainder is 0.000172.
